The terrestrial survey inshore of the invasion beaches identified 60 artifact scatters, miscellaneous debris, pieces of equipment, or Japanese defensive positions. The team revisited 14 archaeological sites previously recorded by Denfeld (1980) and/or by Knecht, Price, and Lindsay (2012) and identified 11 previously unrecorded sites. Biological characterization of the reefs included high-resolution (mm-scale) 3D reconstructions from 424 reef plots. Five UCH sites were modeled providing baseline information on the condition and status of these WWII remains. The side-scan sonar imaged 18 acoustic contacts that were investigated; none resulted in identification of UCH. The magnetomer survey produced 20 anomalies. Of these, 12 were associated with project-located UCH, 7 remain unidentified, but are likely associated with single-point ferrous metal objects consistent with the historic Battle of Peleliu. A comprehensive KOCOA analysis of the invasion beaches and inshore area documented the effects of both defensive and offensive actions on the battlefield. The purpose of this project was to locate the scattered material remains of Peleliu's submerged battlefield, to photogrammetrically record those remains, and to examine the reef substrate and its coral communities to determine if the scars from the UDT 2 mission to blow access ramps into the lagoon were still visible after 74 years. No systematic remote sensing survey of the invasion beaches and adjoining reef line to identify underwater cultural heritage sites (UCH) has ever been undertaken. Previous periods of shoreline development and reef clean-up have already altered the amount and type of WWII sites that are preserved, which directly impacts battlefield interpretation. The location and identification of all remaining UCH sites is critical to understanding the full battlefield on land and underwater.
